The Havoc Squad, also known as Havoc Squadron, was an elite Republic Special Forces squad of troopers in the army of the Galactic Republic, who fought against the Sith Empire during the Great Galactic War. Originally known as infantry squad 326, Havoc Squad soon gained its name under the leadership of its commander Jace Malcom, and it was later led by Malcom's executive officer Jek Kardan, Kardan's protege Harron Tavus, and Meteor. Havoc Squad saw action on many fronts throughout the war, from Ord Mantell to the Battle of Alderaan, and even after the Treaty of Coruscant was signed, the commandos of Havoc Squad continued to combat Sith threats during the resulting Cold War.

They are the army’s most elite fighting team. Despite the total secrecy of Havoc’s missions, the team has taken on an almost superhuman reputation on both sides of the war; unstoppable commandos who can strike anytime, anywhere, regardless of opposition. Before Special Forces existed as a separate division of its own, Havoc Squad was attached to a standard infantry division throughout the Great War. It wasn’t until the Battle of Alderaan that the squad rose to galactic fame, leading a small group of wounded and recovering men to victory against a massive Imperial invasion force. The value of small elite units had been proven, and Havoc Squad was later chosen as the model for a full division of highly trained and agile infantry squads, the Republic Special Forces.
